REVOLVING STENCIL-GYLINQER -MACHINIE 1.

Application filed January 1a, 1926. Serial m. 80,901.

This-invention relates to'improvements in cylinder printing machines fortextile or paper plants, the invention having more particular referencethat is intended to print several colors simultaneously. The inventionhas for an objectthe provision of an improved inking arrangement formachines of the class as here mentioned. For further comprehensionof.the invention, and of the objects and advantages thereof, referencewill be had to the-following description and accompanying drawings,

' and to the appended claims in which the Va.

rious novel features of the invention are more particularly set forth. I

My improved in ing arrangement is adapted to textile or paper printingmachines, of the cylinder type forv printing several colorssimultaneously, and I will therefore describe 1 f briefly a machine ofthis type.

The cloth, silk, linen, wall paper, or other similar material .10 to beprinted is driven over the drum 11, by, means of rotating the drum by abelt extended over a pulley 13, at-

tached to a shaft and to the reduction gear-- ing 14, by means ofwhichthe'mainshaft 15, the bevel gears 16, vertical -shaft 17 and bevel gears18, drive the drum 11, the drum being rotatively supported in the frame19,

to a novel type of machine.

FrICE.

vIcron nosn'ro, or BRONX, New Your as at 20, which also pivotallysupports the shafts 21, by means of the brackets 21 which drive theprinting cylinders 22, by means of shafts 23, andsuitable gears 24 and25, the said printing cylinders 22 being pivoted as at 26, so as to varyth'epressure of the printing roll 22 against the'material 10 tobeprinted, by means of a threaded shaft 27 having a hand wheel 28.

It will be understood that my improved inking arrangement is 3 adaptableto all classes and type of textile cylinder printing machines designedfor printing several col-- ors simultaneously, and that I do notnecessarily confine myself to the particular type or class of machine ashere briefly described.

Referring in particular to my improved inking device, theprinting'cylinders 10, are rotated as heretobefore described,andlcomprises a hollow cylinder 29 having. a plural-- ity of apertures.30, and a covering'31, of

felt or any suitable absorbing material. and a stencil 32, preferably ofbolting cloth or silk, the two latter. named elements being firmlysecured to, the hollow cylinder 29-by means of a clamping devicecomprising a clamping member 33, having an elongated aperture 34, toaccommodate a wing nut 35 or any similar screw, threaded into the end ofthe hollow cylinder, it being understood that the said clamping devicesarelocated at Z The tubular member 37 has an aperture 40,

suitably located at its lower periphery.- The ink container 41 is ofhollowv semi-circular shape, and is attached to the tubular memr 1 her37, as at 41', the heretobefore mentioned construction being such aswill permit the ink which is poured. or otherwise placed in the filler36 to enter theink container 41, throughthe tubular member 37 and theaperture 40. As this inkis to be used to cover tlie stencil 32, it isnecessary that the amount or quantity of same be regulated, and for thispurpose, I have provided a valve artached thereto, as at 47, and havingset" s rews 59 located in slots on the tubular menil'ier 37, so as toallow movement of the hand wheel 46. which will slidably operate thesaid rod 45, .so that the wedges 48 attached thereto will raise or lowerthe, said valve proper 42, by means of the plungers 49, attachedthereto. a slidable lit in the ink container 41, as at 58, and slidablymounted as at 50, the plungers 49 being in contact with-the wedges 48,there being springs 51 super-imposed so as to hold the heads 52 of theplungers 49 against the wedges 48.

In order to assure the proper registering of the ink on the material 10,to be printed,

v I have provided an adjustment as follows:

It being understood that the ends 38 are slidably attached to thedriving inembers 39, as heretobefore stated, the internal gear 53,axially located on one of the ends 38, meshes with the pinion 54,rotatively mounted in the driving member 39, and having a hand wheel 55suitably attached thereto, by means ofwhich the position of the stencil32 may be varied, there being graduations conveniently placed as at 56and a line 57, to. designate the amount of variation thereof.

It is therefore obvious that I have provided a means of inking stencilsand also a mcansof varying the relative positions of the stencils, soasrto assure the proper registering of said imprints with one another,as-is required to properly secure the desired pattern or design to beprinted on the material.

While I have above described the preferred form, construction,am'l'arrangement of the several elements employed, it will be understoodthat the device is, nevertheless susceptible of considerablemodification therein, and I therefore reserve the privilege ofresortingto all such changes as may be fairly embodied within the spiritand scope of the invention as claimed.

Having thus described my invention, what I claim as new, and desire-tosecure by Letters Patent of the -Unit'ed. States is as follows '1. In amachine of the class described, a.

stencil member .of cylindrical .shape, an mkmg member in saidcylindrical member, a concentrically arranged cylindrical pad withinsaid inking member, an ink resermember, having a longitudinal V-shapedopening in the bottom thereof adjacent said inking pad, and alongitudinal V-shaped valve disposed over said opening adapted to beraised and lowered thereinto for controlling the flow of ink from saidreservoir to said inking pad. I

2. In a machine of'the class described the combination 'with acylindrical stencil member rotatively mounted, of a stationary inkreservoir disposed within said stencil member and extending the fulllength thereof. said reservoir having an inlet at the top and adischarge opening at the bottom thereof, valve mechanism disposed oversaid opening for controlling the flow of ink therethrough, a spring fornormally urging said valve upwardly to open said discharge opening andexternally controlled Wedge mechanism for holding said valve mechanismin a suitable position against the pressure of said spring. p

3. In a machine of the class described, an ink reservoir comprising asemi-circular trough having a longitudinal opening extend ng from end toend of the bottom thereof, said opening having bevelled edges, a valvecomprising .a longitudinal Wedge shaped member extending from end to endof said trough, valve rods secured substantially at the ends of saidwedge member and deending' from the frame of said machine, en'-argements on the upper ends of said valve stems, springs for normallyholding said valve stems in an elevated position, and a slidable rodhaving inclined blocks thereon adapted to engage said enlargements andurge said stems and valve downwardly against the pressure of saidsprings.

4. In a machine of the class described, a means of inking. stencils bymeans of a filler attached to a tubular member, llel dstation ary, anaperture located at its lower periphery, an ink conta ner attached tothe said tubular member, and a valve arrangement comprising. a valveproper, extending the entire length of the said ink container, having aV shaped portion to cover an aperture located at and extending theentire length of. the said ink container, and a means of opening andclosing the last mentioned aperture. v

5. In a machine of the class described, a means of inking stencils bymeans of a filler attached toa tubular member, held stationar anaperture located at its lower periphery, 'an ink container attached tothe said tubular member, and a valve arrangement comprising a valveproper, extending the entire length of the saidink container, having a Vshaped portion to cover an aperture located at y and extending theentire length of the said ink container, and a means of opening andclosing the last mentioned aperture, b means of a rod ,slidably being incontact with the said wedges, located in the sai tubular member, havingsprings superimposed so as to hold the a hand wheel attached thereto,which will heads of the said plungers against the said 10 slidablyoperate the said rod so that wedges wedges.
